That's a very important topic to talk about.
Many of the post-docs are carrying over with them the debt they had during their Ph.D., so they have to pay it back either to the government or to the university. The fact is that their low income does not allow them to. That's a simple answer, because their priority is paying their bills; it's not the loan, even though the loan is very important. They are not able to pay off such an expense. It's the second or third priority for them.
If it's coming from the university, it's easier, but they still have have to pay the interest, because the university is adding interest over the years. In the end, it depends on whether or not they end up with a well-paid job, so that they will be able to pay off everything.
I would consider that an important issue, even though I would say that many of the post-docs in our surveys have not indicated that, because, again, there is a higher degree of issues in the list, such that they do not even see that at this point, but I'm pretty sure, based on the people who we have been in contact with, that would be an issue. It definitely would be a good item to include to see what exactly are the numbers that we can talk about in our next survey.
